These awards have given recognition to the innovative design and brilliant safety benefits that the Gun offers.

The Grease Pressure Release Gun is a hand-held safety device which is used to detect the presence of residual pressure trapped behind the grease nipples of lubrication systems in industrial machinery.

The Gun not only detects the residual pressure but also gives a visual indication to advise this condition.

It can then be used to release the trapped pressure from within the system, thereby rendering it safe to work upon.

Before a grease nipple is serviced and/or removed, the Gun’s indicator button – the red button at the back of the device – is pressed in.

This urges the silver rod or piston into its most forward position with the front end of the rod being just in front of the vent (though which any expelled grease is released).

The couple assembly right at the front of the gun is engaged over the grease nipple and pressed into it with the handle. Pressure against the grease nipple causes a slotted pin to depress the grease nipple’s ball.

Because the front surface of the seat, which houses the slotting pin, is in contact with the nipple, any grease pressure, which has accumulated behind the nipple, escapes through the slotted pin.

The escaping grease thus makes contact with the front surface of the rod, urging the rod rearward.

This causes the vent opening to be revealed or uncovered by the rod such that the excess grease can escape through the opening.

Movement of the rod rearward also causes rearward movement of the button bolt, and indicating button at the back of the gun.

If unsure that all the pressure has been relieved, the operator simply needs to retest the nipple by reintroducing the grease coupling after having again depressed the indicating button at the back of the gun.

If the indicating button is fully depressed and the gun is introduced onto the nipple and the indicating button fails to move, there is no longer a dangerous accumulation of grease pressure.

The Gun has a simple design and is easy to use. It also comes with a test block for integrity testing meaning that it can be tested before being placed in an extreme pressure environment.
